OpenSSL is used for all other crypto. For instance the PRNG appears to be OpenSSL: https://github.com/bitcoin/bitcoin/blob/master/src/random.h On Mon, Jan 18, 2016 at 8:39 PM, Andrew C via bitcoin-dev wrote: > In the release notes for 0.12, it says that we have moved from using OpenSSL > to libsecp256k1 for signature validation.
